Patented Mar. 17, 1931 UNITED STATES FFE GUSTAV JOHNSON, 0F WEST ROXBURY, MASSACHUSETTS, ASSEGNO?, TO UNTED- CARR FASTENER CORPORATION, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS Application filed February 2', 1929.

My invention aims to provide improvements in fastener' sockets for snap fasteners.

In the drawings which illustrate a preferred embodiment of my invention Figure l is a vertical section through a snap fastener installation showing the stud in elevation and the socket in cross-section as it appears when the section is taken through the stud-engaging fingers;

Fig. 2 is a section similar to Figure l, eX- cept that the section is taken through the slots between the stud-engaging lingers Fig. 3 is a section similar to Fig. 2, but with the cap part omitted; and

Fig. 4 shows views of the ends of the studreceiving part of the socket.

Referring to the illustrative embodiment of my invention shown by the drawing the stud is of a well known construction and does not form a part of my invention. The simplest form of my improved socket installation is shown in Fig. 3 and, therefore, I shall lirst describe that installation.

The stud-receiving part l is formed from a single piece of sheet metal having a portion 2 at its periphery U-shaped in Cross section and formed by doubling over the peripheral portion of the metal and having a space 2a for purposes hereinafter to be described. The central portion of the part l is pressed out to provide a hollow boss 3 open at both ends. This boss 3 is divided throughout its length by slits 4 thereby providing a number of yieldable fingers 5 (Figs. l and 4) surrounding a stud-receiving aperture.

In order to adapt the fingers 5 for engagement with the neck of the stud, I have turned the free ends inwardly and back upon themselves to provide jaw portions 6.

To secure the stud-receiving part to a flexible socket-carrying medium' or other suitable support 7, I enter the boss 8 through an aperture 8 in the carrying medium 7 so that the U-shaped portion 2 rests against one face of the support. I then present the rivet portion 9 of an attaching element l0 at the opposite side of the support 7 and enter it through the aperture 8. Force is then applied to the metal part of the socket and the rivet engages the curved wall 11 of the boss FASTENER SOCKET Y Serial N0. 337,033.

3 and is bent outwardly and forced into the space 2a. In this manner the carrying inedium 7 is gripped tightly between the parts l and l0 and the socket-engaging partis securely held in position. The rivet portion 9 surrounds the fingers 5 and prevents overexpansion of them.

By making the stud-receiving part l in the manner above described I provide a simple,`

strong and inexpensive socket by using the least possible amount of metal and the number of operations necessary to form it are reduced to a minimum.

1sNhere a neater appearing socket is desired, a cap member l2 (Figs. l and 2) may be secured to the socket-receiving part 1 thereby covering the exposed portions.

While I have shown and described a preferred embodiment of my invention, I do not wish to be limited to the exact structure and, therefore, reference is made to the following claims.

Claims:

l. A fastener socket installation comprising, in combination, a stud-receiving part having a centrally depressed portion providing a boss split into a number of resilient iingers surrounding a stud-receiving aperture, a ring-like portion U-shaped in cross-section, said ring-like portion being formed as a part of said stud-receiving part and including the periphery thereof, said boss having a wall dared outwardly from its free end toward said ring-like portion, a socket-carrying support having an aperture therethrough, said stud-receiving part having its boss extending into the aperture in the said support, and an attaching element having a portion resting against one face of the said support and having a tubular rivet portion extending therefrom through the support in substantially spaced relation to the external portion of the free end of the boss of the stud-receiving part, thereby to permit relatively free flexing of the fingers during engagement with and disengagement from a cooperating stud, and said tubular rivet portion being bent outwardly by said liared wall of said boss into the hollow of the U-shaped ring-like portion CJR to hold the parts of the installation in assembled relation.

2. A socket including a stud-receiving part for a socket installation formed from a single piece of metal and having a portion 2 U- shaped in Cross-section7 a boss 3 open at both ends and divided into a number of lingers 5 and havinga Curved Wall 1l flaring directly into one Wall of said portion 2 for deflecting outwardly the portion 9 of an attaching means 8 into a space 2 provided by the p0rtion 2, and a separate cap member l2 having its peripheral portion crimped over the edge of the portion 2 to secure it to the stud-receiving` part and close the boss 3 at one end.

En testimony whereof, havesigned my name to this specification.

GUSTAV JOHNSON.
